A U-shaped metal bar is placed in the secondary channels, which are then closed at the rear by an outer cover G, so as to facilitate re-starting of the furnace after emptying. The heating units comprise separate blocks C, and two or three such units are detachably mounted on the same side of the furnace wall with respect to the vertical plane containing the rotation axis H, whereby the furnace may be tilted so that the heating units move downwardly to ensure flow of molten metal in the furnace into the secondary channels. The cooling jacket may comprise a chamber F or a metal coil independent of or in series with the primary coil E. The heating units are detachably mounted with intermediate packing e.g. by screws on a curved wall of the crucible B, which may be of semi-circular section and have a pouring spout L. The secondary channels R opening into the crucible may be tubes of metal having a higher melting point than that of the metal to be melted. The furnace may be tilted hydraulically or by a hand wheel and may carry an indicator for the water cooling. The furnace operates at about 30 kW and may be supplied from the mains without a transformer, but an autotransformer may be included to keep the metal molten without overheating. With a three phase supply, the inductor circuits may be connected in series-parallel or delta star. A single phase supply may be used. Each secondary block C has a non-magnetic shell.

Abstract: 594,669. Endless-chain conveyers. MAV OR & COULSON, Ltd., and THOMSON, J. Dec. 8, 1944, No. 24684. [Class 78(i)] In a chain conveyer in which the framework is made up of sections assembled endwise, each section comprising a substantially closed lower housing wherein the lower conveyer run travels and a trough superimposed on this housing for the upper conveyer run, the length of the conveyer is increased by introducing a section sidewise into the framework, one side of the housing of this section being openable to permit the entry of the undivided lower run of the conveyer chain, after which this side is closed. The Figures show the application to a scraperchain conveyer for use in coal mines having a receiving portion built-up of three sections, Fig. 2, each comprising a base component for the lower run of the conveyer consisting of a rectangular plate 19, Fig. 3, reduced in thickness at its edge 20 and provided with a flange 21, and an upper component, Fig. 5, consisting of a trough 22 having hinged side members 24 with flanges 26 which when the side members are vertical extend inwards and serve as a guard over the chains of the upper run 13, and a longitudinal flange 29 which forms one side of the lower housing. The plate 19 has strengthening and locating lugs 31 secured to the flange 21 whilst the trough has supporting webs 30 secured to its sides 23. To lengthen the conveyer, the chain tension is slackened, the upper run parted, the frame structure divided by disconnecting the connecting plates 32 of adjacent sections and the tail end part of the structure pulled back sufficiently to allow the insertion of a section. The plate 19 of the section to be added is now pushed in sidewise below the run 14 of the chain over the floor into the gap in the framework, and the trough component of this section with its sides 24 turned outwards as in Fig. 5. is now placed on top of the plate 19 so that the outermost lugs 31 fit snugly between the webs 30 to lock the components together. The additional chain length is now laid in the trough and connected-up, the sides 24 turned upwards to the position shown in Fig. 8, the.sections connected by bolting the plates 32 and the chain tension re-adjusted.

Abstract: 532,375. Umbrellas. THORENS AKT.-GES., H. Aug. 28, 1939, No. 24720. Convention date, Sept. 27, 1938. [Class 134] The stick of a folding umbrella comprises three telescoping sections 1, 2, 3, Fig. 1, held in extended position by spring catches. The bottom section 1 is carried by a disc 30, Fig. 13, which is held by a spring ring 36 in the open end of the handle 31 when the stick is fully extended, and in the collapsed condition of the umbrella-lies at the bottom of the handle. A fixed rod 34 operates in the section 1, which is tubular, during the opening and closing movements of the stick, and through the medium of a yoke 45 carrying a cross-pin 47 and a wedging block 46 releases and locks the spring latches by which the sections 1, 2 and 3 are held together. The runner 4 is held in its upper position for holding the ribs open by a spring latch 6 carried by a sleeve 52 on the upper stick section 3 ; the latch 38 for holding the stick sections 1, 2 also serves to hold the runner in the closed position of the umbrella. The ribs comprise three sections 13, 19, 24 telescoping into one another. The section 13 consists of two limbs 13<SP>1</SP>, 13<SP>11</SP> of round wire bent into U-shape and pivoted to the head 8 by means of a wire 12. The section 19 is of U- or V-section and carries a slide, 18 to which the stay 5 is pivoted. The stay is also U- or V-sectioned and lies substantially parallel to the section 19 in the closed position of the umbrella. When collapsed,; the limbs 13<SP>1</SP>, 13<SP>11</SP> respectively slide in the channels of the section, 19 and the stay 5, and the end of the latter abuts against a hooked end of the limb 13" in the open condition of the umbrella, to prevent collapse. The section 24 is also U- or V-shaped, and slides on the section 19, being held in extended position by a spring catch 25, which is released when the ribs are being collapsed by an extension of the limb 13<SP>1</SP> of the section 13. When the umbrella is closed, prior to being collapsed, the ends of the ribs are placed around the overhanging projection 67 on the disc 30, which is then moved into the handle 31 and holds the ribs in closed position. The head carries a spring 14 with a series of tongues lying in slots in the head and bearing behind the rib sections 13 to cause them to open slightly when the ends of the ribs are released during the extending movement of the stick.

Abstract: 899,248. Magnetic holding devices. PANTON, J. R., and WEBB, A., [trading as PANTON & WEBB]. July 30; 1959 [July 31, 1958], No. 24764/58. Class 35. In a magnetic work-holder of the type wherein a block 1 of permanent magnets 3 is longitudinally movable relative to a work-holding surface 5 consisting of spaced polepieces 10, 10<SP>1</SP> to render the surface operative or inoperative, the lower edges of the polepieces, which may extend longitudinally or diagonally of the block, are recessed or scalloped to provide spaced " feet " 13, 13<SP>1</SP> which contact the upper faces of the magnets 3 which are slidably mounted transversely on a magnetic base 2. The recesses 12 of the polepieces are so arranged that the " feet " of adjacent polepieces make contact only with magnets of like polarity when the block is in its operative position, as in Fig. 2, in which the series of polepieces 10 contact all the N polarity magnets and the series of polepieces 10<SP>1</SP> all the opposite poles; a holding flux passes through the work between polepieces of opposite polarity until the block is moved to a position in which the polepiece feet span the gaps between adjacent poles, thereby shortcircuiting the flux and releasing the work. The magnets 3 and the polepieces are separated respectively by non-magnetic spacers 4 and 11. In an alternative arrangement, one set of permanent magnets may be replaced by bars of material capable of conducting the flux leaving one set of magnets having like poles uppermost. If it is desired to reduce the workcontacting faces of the polepieces to an area providing approximately the same flux-density as that at the faces in contact with the magnets the polepieces may be of tapered section, as shown in Fig. 3, or to provide a more constant horizontal cross-sectional area they may be formed as shown in Fig. 4.
